Avoid repeat SAXParserFactory instantiation ------------------------------------------- Key: JBPM-858 URL: http://jira.jboss.com/jira/browse/JBPM-858 Project: JBoss jBPM Issue Type: Patch Components: Core Engine Affects Versions: jBPM 3.1.4 Environment: XP, jdk1.4, jBPM-3.1.4 Reporter: Johan Parent Assigned To: Tom Baeyens Priority: Minor Repeated instantiation of a SAXParserFactory object is both unnessary and results in many lookup for system properties which are not present. Hence causing extra work and I/O. Simple patch to JpdlParser.java should fix this. WARNING: could not test this code .............. public class JpdlParser implements Serializable { private static final long serialVersionUID = 1L; static final EntityResolver JPDL_ENTITY_RESOLVER = new JpdlEntityResolver(); // // Avoid repeated instantiation of SAXParserFactory, especially the expensive FactoryFinder.find() // calls it implies. Define factory as static and init in static block // private static SAXParserFactory saxParserFactory; ....................... static { saxParserFactory = SAXParserFactory.newInstance(); saxParserFactory.setValidating(true); saxParserFactory.setNamespaceAware(true); } ................. public static XMLReader createXmlReader() throws Exception { /* SAXParserFactory saxParserFactory = SAXParserFactory.newInstance(); saxParserFactory.setValidating(true); saxParserFactory.setNamespaceAware(true); */ SAXParser saxParser = saxParserFactory.newSAXParser(); XMLReader xmlReader = saxParser.getXMLReader(); ................. -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: http://jira.jboss.com/jira/secure/Administrators.jspa - For more information on JIRA, see: http://www.atlassian.com/software/jira
